OpenGL extension SGI.texture_color_table
This module customises the behaviour of the OpenGL.raw.GL.SGI.texture_color_table to provide a more Python-friendly API
Overview (from the spec)
This extension adds a color lookup table to the texture mechanism. The table is applied to the filtered result of a texture lookup, before that result is used in the texture environment equations.
The definition and application of the texture color table are similar to those of the color tables defined in SGI_color_table, though it is not necessary for that extension to be implemented.
Texture color tables can be used to expand luminance or intensity textures to full RGBA, and also to linearize the results of color space conversions implemented by multidimensional texture table lookup.
This specification has been updated to define its interaction with multitexture.
